Hi John,

It's too bad your window does not lend itself to the spacer-with-holes
approach, as I was also going to suggest that. Does that non-removable
screen have a wide frame? If so, maybe you could go through holes
in a window spacer, then through holes in the screen frame.

In any case, you could save yourself one of those holes in the wall by
letting your "ground" wire and the coax share one hole.

Better yet, you could forget about the "ground" wire altogether--at least
if you have a third-wire ground in your AC sockets. A long "ground"
wire will be too puny and inductive to be any kind of RF ground. And
if you have a power ground through the AC socket, adding a parallel
ground path will just confuse things, increase your lightning risk, and
possibly put you into a code violation.

I have only AC-socket power grounds in my second floor shack, and
I run QRO on 80 through 10 with no problems.

My shack is on the second floor, and I will be feeding a vertical with
RG-213/U. In addition to the antenna feed line, I will also need to run a
wire from the shack to a ground rod. The room housing the shack has one
window, which is just to the left of the equipment table, and the window
is
an aluminum single-hung type. The house wall has aluminum siding on the
exterior.

My current plan is to drill two holes, one for the coax and one for the
ground wire, in the wood frame that is just below the bottom of the
window.
I expect to sell this house in the next year or two, so I want to be able
to
easily patch over any holes I have made in the wall.

Any advice and information will be gratefully received.




Replace glass with a sheet of "Lexan" or "Perspex". Then you can drill all
the holes you like. If you move out, put the glass back in.

Thanks for your suggestion, but among other things that sheet of plastic
would get all frosted in the winter (it gets down to 0° F here), and the
heat loss through the pane (roughly 27 X 27") would be quite large. Finally,
the window has an aluminum frame and to remove either window is a big pain.
